The owner of the large, off-site plot showed particular interest and eagerness for the sustainable construction of his home. The nearly 5 acres of flat land of his land proved particularly suitable for the choice of applying shallow geothermal energy.
The installation of a slinky, closed-loop horizontal geo-alternator (closed loop at a depth of up to 3 meters or until an existing aquifer) and a water-to-water geothermal heat pump connected to an underfloor cooling-heating system were selected. The completely silent geothermal pump is placed in a special “cabinet” inside the house. As an auxiliary heating system is installed a 19 KW energy fireplace (consumption 5.5 kg / h) with 75% + energy efficiency. For cooling, the geothermal system assists with bioclimatic techniques (planting, aperture permeability, summer azimuth shading calculation).
The very large, south-facing and overlapping glazing units are wooden (heat-cut) with triple energy glass panels with 4-4-5 and UVA – UVB filters. The stone stoneware of Ioannina cans are heat storage facilities in the Southeast and heat breakers in the Northwest.
The roofs were designed as rainwater harvesting seals (which will be concentrated in an adjacent natural flow tank) and with the prospect of receiving autonomous or connected photovoltaic panels. Adding photovoltaics will allow the home to be categorized into a virtually zero-energy building (A +). In the event of no photovoltaic installation, the roof is “ready” to be planted with low and medium height grasses and shrubs, significantly increasing the heat capacity of the dwelling.
All materials used are “indigenous” inorganic raw materials, recycled and reusable organic PU etc “plastic” materials. The deck on the terraces is made of natural wood. Paints, varnishes and other coatings are all eco-friendly materials. The liquid waste tank was designed to operate biologically.
